PRINTING AND VIGNETTING FRAME.

SPECIFICATION forming part of Letters Patent No. 440,399, dated November 11, 1890.

Application filed April 7, 1890. Serial No. 346,843. (No model.)

To all whom it may concern.-

Be it kn own that we, \VALLAOE EASSON and \VALTER EASSON, of Racine, in the county of Racine,and in the State of isconsimhave invented certain new and useful Improvements in Printing and Vignetting; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to printing and vignetting; and it consists in certain peculiarities of construction and combination of parts in connection with a photographic-printing frame, as will be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a frontelevation of our device with parts broken away; Fig. 2, a longitudinal section; Fig. 3, a transverse section; Fig. 4:, a detail view of a tallying device, that constitutes part of our invention; Fig. 5, a similar view illustrating a tissue-paper holder, that also constitutes part of said invention; Fig. 6, an elevation, partly in section, of the parts illustrated by the preceding figure; and Fig. 7, a perspective view of a device constructed according to our invention.

Referring by letter to the drawings, A represents a frame, having a back composed of sections B, hinged together and provided with pivotal spring-clamps C, the latter being turned on their pivots to bring their ends under disks D on the frame when it is desirable to secure said back in place, the construction thus far described being well-known in the art to which our invention relates.

Inclined kerfs b are cut in the ends of the frame A to serve as guides for the turnedover ends 0 of a laterally-adjustable sheetmetal plate E, that has a central opening approximately equal to the interior of said frame. The plate E is also provided with flanges d, that form guides for a vertically-adjustable plate F, the latter having a central opening e and an annular seat f for a rotary adjustable disk G, this disk being held against its seat by a flanged ring H, provided with ears g, bolted or otherwise suitably secured to the vertically-adjustable plate. The disk G is provided with a central beveled opening it in register with the opening 0 in the vertically-adj ustable plate F, and a handled is secured to said disk to facilitate its rotary adjustment.

As shown in Fig. 1, the laterally-adjustable plate E may have extensions j beyond its flanges d, in order to prevent exposure of the opening in the frame A when said plate is moved in either direction far enough to bring the openings in the vertically-adjustable plate F and rotary adjustable disk Gr adjacent to the opposite limit of said frame-openfive prefer to provide the vertically-adjustable plate F with a clamp made from a single piece of spring-wire I bent to surround the rotary adjustable disk G and terminate in coils k and hooked extensions m, the latter being inserted in said plate and held in place by a staple n, as best illustrated in Fig. 5, the spring-clamp serving as a means for holding a sheet of tissue-paper over the opening h in said disk, in order to soften the light admitted through said opening and diffused by the increasing area thereof due to the bevel. (Best illustrated in Fig. 7

One side of the frame A is preferably recessed to receive a circular pivotally-adjustable plate J, provided with a handle 19 and notched at regular intervals upon its periphery to engage with a spring-dog K, the notches being preferably numbered, as is best illustrated in Fig. i.

The device above described is to be employed for vignetting, and to this end the three adjustments above described are employed to bring the opening h in the disk G over that portion of a negative it is desirable to print, said negative being held in the frame A against the plate E by means of the springelamped back, as is usual in the art.

By means of the pivotally-adjustable circular plate J, having the notched periphery, and the spring-dog K the printer is enabled to keep a correct tally of the number of positives obtained, said plate being turned one notch for every print made from the negative.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with a photographicprinting frame, of a laterally, vertically, and

rotary adjustable vi gnettin gdevice connected thereto, substantially as set forth.

2. The combination, with a photographicprinting frame, of a vignetting-plate connected thereto, a tissue-paper clamp consisting of a bent spring-wire terminated in coils, and a device for holding extensions of the coils to said vignetting-plate, substan tially as set forth.

3. The combination, with a photographicprinting frame, of a vignetting-plate connected thereto, a tissue-paper clamp consisting of a bent spring-wire terminated in coils and hooked extensions, the latter being inserted in the vignetting-plate, and a staple for holding said extensions in place, substantially as set forth.

4. The combination, with a photographicprinting frame having kerfs cut in .the ends thereof, of a plate having an opening approximately equal to the interior of the frame and turned-over ends engaging said kerfs and a vignetting device carried on the plate, substantially as set forth.

5. The combination, with a photographicprinting frame, having kerfs cut in the ends thereof, of a plate having an opening approximately equal to the interior of the frame and turned-over edges engaging said kerfs, another plate ajustablc on the first and provided with a central opening, and a vignetting device arranged in the latteropening, substantially as set forth.

6. The combination, with a. photographicprinting frame, of a plate arranged thereon and provided with an opening, a rotary adjustable disk seated in the opening, and a flanged ring arranged on said plate to hold said disk against its seat, substantially as set forth.

In testimony that We claim the foregoing we have hereunto set our hands, at Racine, in the county of Racine and State of Wisconsin, in the presence of two witnesses.
